n'To a'ZZ whom it may concern:

Be it known that I, lVILLIA D. KIRK- PA'iRIoK, a citizen of the United titatesj residing'at Itasca, in thecounty of Hill State ofTeXas, have invented certain new and useful Improvementsin Cultivator Attachments, of which the followingisaspecificati'on. W

- .YThis invention it "relates to cultivator attachmentsandhas for its object the jprovi .sion of a soilengaging member whichcooperates withxthe cultivator to completely pre- 1 which maybe conveniently connected to 20 {The above and other objects of this inpare the soil to' receive the seed, thereby eliminating the double operation of first plowing and then cultivating the soil.

Another object of the inventionfis to provide an attachment of the above nature standard types of cultivator-s without interfering with the use of the latter.

vention will be in part described and in part understood from the following description of the present preferred embodiment of the invention taken in connection with the accompany ng drawings, where nzf Fig. 1, is a top plan viewof the device constructed m accordance wlththis nvention. i I r i c, Fig. 2, is a side elevational view partly in section and part thereof being broken manner of connecting, and

Flg. 4:, 1s a side elevat onal view, .partly i insection of the presser bar.

In the drawings, a pair of cultivator beams 5 are shown which havecultivators 6 connected thereto in the usual way. The front ends of the beams are detachably connected with the spindles of the cultivator arch 7,. which may also be of the usual or any desired configuration. A hobble memher 8 is connected with saidbeams approximately midwaythe ends of the latter to limit outward movement of the latter for a purpose hereinafter set forth.

c The device of this inventionconsists especiallyvof a presser bar generally designated 9 and consistsof a main body bar lO which is arched midway its ends as indicated at 11.

i face of the bod bar, eachof said straps hav A pair of straps 12 are secured to the top ing one end t ereof engaged adjacent" the watched and and the opposite end. thereof detail fragmentarybottoin plan of the presser bar, illustrating its branches are recessed as indicated at 23, ad-

jacent the free terminals thereof, adapted i for the reception of a bolt 24 which extends transversely through the beam 20. This bolt offset upwardly soas to lie in parallelism gated lockinglink 16 isslidablymounted on the'l'ower face of the body bar andis pro vided with an elongated slot 17 throu h whichthe shank of the stud eXten s.

The head of said stud is engaged with the outer face of saidrlink to hold the latter from displacement. The end of the link 16 opposite mam which is engaged by the stud 15 is provided with a semicircular recess as indicated by the dotted line 18 in Fig. 3. This recess is .engageable with the shank of the stud 13 and is held in engagement therewith by a locking pin19avhich extends through the body bar and into the locking link as illustrated in Fig. 4E.

i The free ends of'a plow beam 20 are connected with the spindles of the arch 7 within the cultivator beams Thisbeam extends through the arch 11 of the body bar and is pivotally connected by means of a bolt 21 to the foot 22 of the beam.

Said foot is bifurcated at one end and the branches of the bi furcation straddle across the inner end of the beamQO. The upper edges of said has anut mounted on its outer end whereby the branches are normally held snugly in engagement with the opposite side'of the beam 20. i A plow 25 of any suitable design is provided which has upstanding therefrom a shanlr 26, the latter extending through an eye-bolt 27, which extends through the bill. of the shoe 22 and is detachably connected therewith. The shank latter, such, for instance, as by contact with root, stone, or the like, the branches of. the

bifurcationwill be disengaged from the bolt 2a andthe shoe 22permitted to swing on its axis 21.

If desired, the beams 5 may be permitted i to ride freely between the body bar 10 and the straps 12, undue lateral movement of said beams, being prevented by the hobble 8. However, when it is desired to furrow the soil, bolts 28 are used, one being mounted on each side of each beam in order tohold the same from lateral movement as illustrated to advantage in Fig. L If desired, a series of bolt openings may be formed in the presser bar so as topermit a greater range of adjustment of the beams. I 7

By connecting the beams to the presser bar in a manneras described above, the plow 25 will be pressed downwardly into the'soil by the pressure of the beams 5. Since the plow operates in front of the cultivators 6, it will be=obvious that the soil will be simultaneousl uplowed and cultivated. When it is desired to disengage the plow beam 20 the pin 19 is removed and the locking link 16 retracted. across the stud 15, thereby'openin the mouthof the arch 11.

v Vhat is claimed is:

a LA cultivator attachment, in combination with an arch having cultivator beams and a plow beam connected thereto a'presser bar including an integral bar body provided with a relatively small inverted U-shape arch which snugly embraces said plow beam, means to hold said plow beam in said arch, and a pair of straps the inner end of each of which is secured to said bar adjacent its U- shape arch, the opposite ends of the straps being arranged in spaced parallel relation to the bar to receive the cultivator beams between said bar and straps substantially as described. 7

2. A cultivator attachment in combination with an arch having cultivator beams and a plowbeam connected thereto, a presser bar arched midway its ends and receiving the plow beam in the arch, the opposite ends of said bar being extended into engagement with the cultivator beams, and means to se cure said beams from displacement on the bar.

In testimony whereof I afiix my signature in presence of two witnesses.
